It's an idea I had the other day as well. Back when mainly Disc Priests roared for more survivability.

When they buffed Levitate from 2 minutes to 10 I figured they were going to do something with it. They didn't.
So, I figured they could give us a talent that has a 50%/100% to negate particular roots and snares cast by a player.

Mainly to stop Frost Mages, without being broken, in my opinion. I mean, they have Spellsteal, so they can get rid of Levitate, and have the occasional Fingers of Frost proc.

Well, they can remove or change Body and Soul so that Levitate doesn't break on damage when cast on the priest, and makes you able to mount with the levitate buff. That makes it more useful.That's a joke
